Compressor shuts off before reaching pressure
by jon dee
compressor shuts off without reaching full operating pressure (circuit breaker trips)
Make sure the power supply to your Harbor Freight air compressor is "clean". By that, I mean no extension cord being used, and no other appliances pulling power from the same circuit the air compressor is on.
If the problem persists when you have clean power, then it might be a failing pressure switch allowing a short and popping the breaker, it could be the motor is laboring and pulling too many amps, it could be the start/run capacitor isn't working right... many things.
What pressure does it reach before the breaker pops, and is the breaker popping at the same pressure on the compressor every time?
Post a response here please, if you wish, so I can follow the thread.
